PURGE VALVE INSPECTION

PROCEDURE


  1. INSPECT PURGE VSV (w/ Canister Pump Module)


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 23 to 26 Ω
      1 - VSV body ground Always 10 MΩ or higher
      2 - VSV body ground 10 MΩ or higher

      If the result is not as specified, replace the purge VSV.

    2. Check the operation of the purge VSV.


      1. A01HDZ7C01
        *a Port E
        *b Port F
        B008IUL Air

        Check that air does not flow from port F when air is applied to port E.

      2. A01HES6C03
        *a Port E
        *b Port F
        B008IUL Air

        Apply battery voltage to the connector, and check the VSV operation.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → Terminal 1

        Battery negative (-) → Terminal 2

        		 Air flows from port E to port F

        If the result is not as specified, replace the purge VSV.

  2. INSPECT PURGE VSV (w/o Canister Pump Module)


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 23 to 26 Ω
      1 - VSV body ground Always 10 MΩ or higher
      2 - VSV body ground 10 MΩ or higher

      If the result is not as specified, replace the purge VSV.

    2. Check the operation of the purge VSV.


      1. A01HJGNC02
        *a Port E
        *b Port F
        B008IUL Air

        Check that air does not flow from port F when air is applied to port E.

      2. A01HFIPC02
        *a Port E
        *b Port F
        B008IUL Air

        Apply battery voltage to the connector, and check the VSV operation.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → Terminal 1

        Battery negative (-) → Terminal 2

        		 Air flows from port E to port F

        If the result is not as specified, replace the purge VSV.

  3. INSPECT NO. 1 CHECK VALVE


    1. Install a clean hose to the No. 1 check valve.

    2. Check the No. 1 check valve operation.


      1. A01HHT7C01
        *a Purge VSV Side
        B008IUL Air

        Blow air into the purge VSV side and check that air passes through easily.

        If the result is not as specified, replace the No. 1 check valve.

        CAUTION:

        Do not suck air through the valve.

        Petroleum substances inside the valve are hazardous to your health.

      2. A01HHSIC01
        *a Intake Manifold Side
        B008IUL Air

        Blow air into the intake manifold side and check that air passes through with difficulty.

        If the result is not as specified, replace the No. 1 check valve.
